Halogenation process

Claim 2

IN A CONDENSATION REACTION WHEREING A HYDROCARBON IS CATALYTICALLY RACTED WITH HALOGEN IN THE PRESENCE OF OXYGEN, THE IMPROVEMENT WHICH COMPRISES; TREATING THE REACTION MIXTUURE IN THE REACTION ZONE WITH AT LEAST 10 PARTS BY WEIGHT OF DESICCANT SOLIDS BASED ON OXYGEN AND IN AN AMOUNT SUFFICIENT TO DEHYDRATE THE VAPOROUS REACTION MIIXTURE IN THE REACTION ZONE; SAID AMOUNT OF DESICCANT BEING UNADMIXED WITH, AND INDEPENDENT OF, ANY MATERIAL USED AS SUPPORT FOR THE CATALYST.

Claim 3

IN A CONDENSATION REACTION WHEREIN A HYDROCARBON IS CATALYTICALLY REACTED IN A REACTION ZONE WITH HALOGEN IN THE PRESENCE OF OXYGEN, THE IMPROVEMENT WHICH COMPRISES: ALTERNATELY TREATING THE REACTION MIXTURE WITH A SOLID HALOGENATION CATALYST AT REACTION TEMPERTURE IN A SOLID CATALYST CONTACTING ZONE AND THEN WITH DESICCANT SOLIDS IN A SEPARATE ZONE AT A TEMPERATURE BELOW THE TEMPERATURE OF THE SOLID CATALYST CONTACTING ZONE; SAID DESICCANT BEING IN AN AMOUNT OF AT LEAST 10 PARTS BY WEIGHT BASED ON OXYGEN AND SUFFICIENT TO DEHYDRATE THE VAPOROUS REACTION MIXTURE IN THE REACTION ZONE AND SAID AMOUNT OF DESICCANT BEING UNADMIXED WITH, AND INDEPENDENT OF, ANY MATERIAL USED AS SUPPORT FOR SAID CATALYST; CONTINUOUSLY REMOVING THE DESICCANT FROM THE REACTION ZONE BEFORE ITS WATER SATURATION LIMIT IS REACHED; AND CONTINUOUSLY REPLACING THE WITHDRAWN DESICCANT WITH DRY DESICCANT AT A TEMPERATURE BELOW THE TEMPERATURE IN THE REACTION ZONE.

Claim 4

IN A CONDENSATION REACTION WHEREIN A HYDROCARBON IS CATALYTICALLY REACTED IN A REACTION ZONE WITH HALOGEN IN THE PRESENCE OF OXYGEN, THE IMPROVEMENT WHICH COMPRISES: ALTERNATELY TREATING THE REACTION MIXTURE WITH A SOLID HALOGENATION CATALYST AT REACTION TEMPERTURE IN A SOLID CATALYST CONTACTING ZONE AND THEN WITH DESICCANT SOLIDS IN A SEPARATE ZONE AT A TEMPERATURE BELOW THE TEMPERATURE OF THE SOLID CATALYST CONTACTING ZONE; SAID DESICCANT BEING IN AN AMOUNT OF AT LEAST 10 PARTS BY WEIGHT BASED ON OXYGEN AND SUFFICIENT TO DEHYDRATE THE VAPOROUS REACTION MIXTURE IN THE REACTION ZONE AND SAID AMOUNT OF DESICCANT BEING UNADMIXED WITH, AND INDEPENDENT OF, ANY MATERIAL USED AS SUPPORT FOR SAID CATALYST; CONTINUOUSLY REMOVING THE DESICCANT FROM THE REACTION ZONE BEFORE ITS WATER SATURATION LIMIT IS REACHED; AND CONTINUOUSLY REPLACING THE WITHDRAWN DESICCANT WITH DRY DESICCANT AT A TEMPERATURE BELOW THE TEMPERATURE IN THE REACTION ZONE.

Claim 5

A CONTINUOUS PROCESS FOR THE PRODUCTION OF AN ORGANIC HALOGEN-CONTAINING COMPOUND WHICH COMPRISES THE STEPS IN COMBINATION: A REACTION ZONE CATALYTICALLY REACTING A HALOGEN WITH A HALOGENATABLE OLEFIC HYDROCARBON TO PRODUCE A REACTION MIXTURE WHEREIN LESS THAN 50 PERCENT OF THE DESIRED ALOGENATION CONVERSION IS EFFECTED; CONTACTING THE RESULTING REACTION MIXTURE WITH OXYGEN, HYDROGEN HALIDE AND AT LEAST 10 PARTS BY WEIGHT OF A SOLID DESICCANT BASED ON OXYGEN SAID AMOUNT OF DESICCANT BEING INDEPENDENT OF ANY MATERIAL USED AS SUPPORT FOR THE CATALYST; CONVERTING AN ADDITIONAL PORTION OF THE HYDROCARBON TO HALOGENATED HYDROCARBON AND MAINTAINING AN ANHYDROUS REACTION MIXTURE BY ABSORBING WATER FROM THE VAPORS AS SOON AS IT IS FORMED IN THE REACTION ZONE BY SAID SOLIC DESICCANT.

Claim 6

A CONTINUOUS PROCESS FOR THE PRODUCTION OF AN ORGANIC HALOGEN-CONTAINING COMPOUND WHICH COMPRISES THE STEPS IN COMBINATION: A REACTION ZONE CATALYTICALLY REACTING A HALOGEN WITH A HALOGENATABLE OLEFIC HYDROCARBON TO PRODUCE A REACTION MIXTURE WHEREIN LESS THAN 50 PERCENT OF THE DESIRED ALOGENATION CONVERSION IS EFFECTED; CONTACTING THE RESULTING REACTION MIXTURE WITH OXYGEN, HYDROGEN HALIDE AND AT LEAST 10 PARTS BY WEIGHT OF A SOLID DESICCANT BASED ON OXYGEN SAID AMOUNT OF DESICCANT BEING INDEPENDENT OF ANY MATERIAL USED AS SUPPORT FOR THE CATALYST; CONVERTING AN ADDITIONAL PORTION OF THE HYDROCARBON TO HALOGENATED HYDROCARBON AND MAINTAINING AN ANHYDROUS REACTION MIXTURE BY ABSORBING WATER FROM THE VAPORS AS SOON AS IT IS FORMED IN THE REACTION ZONE BY SAID SOLIC DESICCANT.
